International consensus (ICON) on basic voice assessment for unilateral vocal fold paralysis

Area of Science:

• Otolaryngology
• Speech and Language Pathology
• Medical Diagnostics

Background:

• Standardized voice outcome assessment tools are needed post-laryngeal surgery.
• Previous consensus protocols, like the Dejonckere protocol, have seen limited adoption.
• A significant gap exists between proposed multidimensional voice assessment methods and actual clinical practice.

Framework:

• The study proposes a simplified, practical protocol for voice outcome evaluation.
• Focus is placed on unilateral vocal fold paralysis (UVFP) as a model due to its physiological homogeneity.
• The protocol is informed by literature review and expert consensus from the IFOS panel.

Implementation:

• Mandatory components include voice audio recordings and systematic use of the Voice Handicap Index (VHI).
• Perceptual analysis should utilize Hirano's GRB scale, prioritizing the assessment of voice breathiness.
• Acoustic analysis is currently optional, while aerodynamic assessment should include Maximum Phonation Time (MPT).

Implications:

• This protocol aims to improve the consistency and reliability of voice surgery outcome evaluation.
• Standardized assessment can aid in clinical decision-making and medico-legal documentation.
• The proposed framework offers a more accessible approach to quantifying voice function and patient-reported outcomes.
